The Lenovo Legion Slim 5i boasts better performance for 3D tasks, machine learning, and gaming thanks to a dedicated Nvidia RTX GPU, but it's heavier, which may affect portability. If you prioritize longer battery life, a much lighter chassis, and sufficient power for general use and engineering tasks without intensive graphics, the LG Gram 16 offers an impressive balance between performance and portability. Both laptops have a high-resolution display and are similarly priced, so your choice should consider whether you need the extra graphics performance or a more travel-friendly device. Give Feedback

The Lenovo Legion Slim 5i has a better screen than the LG Gram 16 for general use, gaming and AI, engineering and design, and content creation.
For general use, both the Lenovo Legion Slim 5i and the LG Gram 16 offer displays with ample resolution and brightness, making text and images clear and vibrant, with the panel technology providing wide viewing angles and consistent colors. When discussing suitability for engineering and design, both laptops have displays that cover a broad spectrum of colors, crucial for precise color work, but they may differ in exact color gamut coverage, which affects how accurately colors are reproduced. However, for gaming and 3D tasks, the lower refresh rates on these two models can result in less fluid motion and slower response times, which are less optimal for fast-paced visuals that require smooth, real-time rendering.

Mark Knapp | August 2023
"The Lenovo Legion Slim 5 Gen 8 acknowledges that a gaming laptop doesn’t have to be as thick as possible and can still ensure adequate cooling when the muscles need flexing. To this end, in the Slim 5 Gen 8, it finds a neat balance of refined, trimmed-down design that still lets its internals cruise (even above their max power ratings). Lenovo then added in some high-end build quality with an altogether excellent keyboard that’s useful for both work and play."

"The LG Gram 16 is a lightweight device with stability issues. The LG Gram 16Z90Q with a Core i7-1260P is made with portability in mind and places less of a focus on users with high demands on performance. The compact and light chassis is particularly practical when you are on the go. The device is not only comfortably small and lightweight, it also boasts a great battery life. When connected to mains, on the other hand, the 16-inch device is rather disappointing. The standard cooling mode causes extreme volatility in terms of CPU, SSD and iGPU performance. The meager stability of the chassis may also put off some potential buyers."
